It remains to be noted that:
- On PC a traditional RS232 serial interface is available (no longer soooo usual) or
- A "USB to serial" - adapter can be used (there is to buy). The latter could create problems under Linux, but not necessarily
- The "transfer program" of the cam manufacturer (especially for users of Windows) and
- The current firmware was downloaded
An installation guide can be found in the download of the "transfer program"
All in all a very good buy in order to remain flexible with his subscription from Germany's major pay-TV provider in terms of the hardware used.
